COMBINED ELECTRIC STOVE AND IRONING DEVICE Filed March 2, 1934 2 Sheets-Sheet 2 Patented May 28, 1935 UNITED STATES PATENT OFFICE COMBINED ELECTRIC STOVE AND IRONING DEVICE 11 Claims.

This invention relates to electrical appliances and more particularly to a combined electric heating and ironing device.

The object of the invention is to provide a combined heating and ironing device of simple and durable construction especially adapted for use by seamstresses, dressmakers, tailors and others for pressing out seams, tucks, hems and other portions of a garment or for ironing lace, doilies, or similar delicate fabrics and which may be readily converted into a stove when it is desired to cook or heat liquids or diiferent kinds of foods.

A further object of the invention is to provide a device of the character described capable of being quickly attached to a sewing machine table or other support so as to be in convenient reach of a seamstress using the same and which will always be ready for immediate use thereby enabling the seamstress to press seams or other portions of a garment without the necessity of stopping work and heating the ordinary domestic sadiron usually employed for this purpose.

The invention has for a further object the provision of a combined heating and ironing unit mounted for pivotal movement and so constructed that, when it is swung downwardly on its pivot to a horizontal position, it may be used for ironing purposes and when swung upwardly to a vertical position may be used as a stove.

The invention further contemplates the provision of a cylindrical casing or jacket surrounding and mounted forrotation on the heating unit and constituting an ironing surface on which fabric may be placed and efliciently ironed or pressed without danger of scorching or otherwise damaging the fabric.

A still further object of the invention is gen erally to improve this class of devices so as to increase their utility, durability and efficiency.

Figure 5 is a transverse sectional view taken on the line 5-5 of Figure 2.

The improved combined ironing device and stove, forming the subject-matter of the present invention, comprises a bracket 5 adapted to extend over the edge of a sewing machine table or other suitable support 6 and provided with an inwardly extendingarm l in which is threaded a clamping screw the inner end of which is adapted to bear against the bottom of the table and firmly secure the bracket in position thereon. The bracket 5 is provided with spaced upstanding ears 9 and fitted between said ears are arms 50 of a substantially U-shaped base support, indicated at E2. interposed between the arms ID of the base support is a spacing sleeve l3 and extending through said sleeve and likewise through the arms l0 and ears 9 is a bolt 14 which forms a pivotal connection between the bracket and base l2, said bolt being provided with a wing nut l5 by means of which the base may be clamped in difierent positions of adjustment with reference to the supporting bracket. Threaded in the closed end of the support I2 is a rod or shaft l6 having a terminal recess or socket I! in the outer end thereof and adapted to receive a centering boss or bearing I 8 extending inwardly from the adjacent end of a cylindrical jacket or casing I 9 constituting an ironing surface. The inner end of the casing I9 is cut away to form a stop shoulder 20 defining a circumferential flange 2| and engaging said flange and shoulder and retained in position by screws 20 is a ring or collar 22 which bears against an end plate 23 forming a stationary closure for the inner end of the casing Hi; It will, of course, be understood that in actual practice there will be sufiicient space between the end plate 23 and ring 22 to allow for expansion and contraction of the casing l9 when the latter is heated. The

end plate 23 is threaded on the rod l6, as indi- Secured in any suitable manner to the rod 96 is a cylindrical core 26 formed of porcelain, bakelite, isinglass or other suitable insulating material, and the walls of. this core are provided with spaced longitudinally disposed grooves 2? in which are seated heating cdils 28 of standard construction. The coils 28 are connected in series and the terminals 29 of the wires constituting the coils are connected with a suitable socket plug 30 seated in the end plate 23 and also of standard construction. The plug 30 coacts with a mating plug 3! secured to an electric conductor 32, the plug 3! being provided with a standard cut-off switch 32 so that by opening the switch and inserting the prongs of the plug 3! into the sockets of the plug Bil the heating coils may be connected in an ordinary house circuit for effecting heating the device. If desired, however, the plug 3% may be omitted and the terminals of the coils extended through suitable openings in the end plate 23 for connection with any suitable source of electric current. As previously stated, the coils 28 are for the purposeof heating the revolving casing l9 when the device is used for 25,

pressing or ironing fabric. In order to heat the end or top 33 of the casing I9, when the device is swung upwardly and used for heating or cooking purposes, the adjacent end of the core 26 is formed with a substantially spiral groove 34 in which is seated a supplemental heating coil 35, the terminals of which are connected with an auxiliary plug 36 similar in construction to the plug 30. It will be noted that the rod i6, core 26, and end plate 23 are stationary while the casing 19 is free to revolve around the same, being guided in its rotary movement by the centering boss l8 and the collar or ring 22 bearing against the peripheral edge of the end plate 23 and this rotary movement of the casing l9 serves to prevent accidental scorching or damaging of fabrics when said fabrics are placed on the ironing surface of the casing and a reciprocating motion imparted thereto to effect the ironing thereof.

In operation, the device is positioned on a table or other suitable support by passing the arm I of the bracket beneath the support and tightening the clamping screw 8, as best shown in Figure 2 of the drawings. When the device is to be used'for ironing or pressing seams, hems, tucks, or other portions of a garment, or for ironing collars, handkerchiefs, or other delicate fabrics, the clamping nut 05 is loosened and the heating element swung downwardly to the horizontal position, shown in Figure 1 of the drawings, and in which position it may be firmly secured by tightening-said nut. It will be obvious that by placing the goods to be pressed on the ironing surface of the casing I9 and imparting a slight reciprocating movement to the goods the seams of the garment will be effectually pressed and, inasmuch as the casing is free to rotate on the core, liability of concentration of the heat at any particular point on the periphery of the casing and consequent scorching or other damage to the fabric is effectually eliminated. It will, of course, beunderstood that after the device is swung downwardly to a horizontal position, the prongs of the plug 3! will be introduced within the sockets of the plug 30 so'that the coils 28 will be connected in the house circuit and heating of the. coils and ironing surface thereby effected.

When it is desired to use the device for heating water, coffee, or other commodities, the screw i5 is loosened and the heating unit swung upwardly to the dotted line position shown in Figure 2 of the drawings, after which the wing nut 55 is tightened so as to hold the heating unit in an upright position and in which position the top 33 of the casing may be used as a support for a vessel containing the liquid or food to be heated. When the heating unit is used as a stove, the plug 3! will be removed from the socket 30 and inserted in the socket 35 so that the supply of current to the coils 28 will be automatically cut off and the coils 35 heated to supply the necessary heat for cooking purposes.

In some cases it may be found desirable to employ a switch of standard construction connected with the heating coils for cutting out one or more of the coils thereby to vary the degree of heat.

It will, of course, be understood that the devices may be made in different sizes and shapes and constructed of any suitable material and supplied with any number of heating coils without departing from the spirit of the invention.

From the foregoing description, it is thought that the construction and operation of the device will be readily understood by those skilled in the art and further description thereof is deemed unnecessary.
